New CDF results on diffraction

we report new diffraction results obtained by the cdf collaboration in proton-antiproton collisions at the fermilab tevatron collider at ？s = 1.96 tev. the first experimental evidence of exclusive dijet and diphoton production is presented. the exclusive results are discussed in context of the exclusive higgs production at lhc. we also present the measurement of the q2 and t dependence of the diffractive structure function.
